    Description / Table of Contents: Eine kinetische Untersuchung der durch Trichloracetylchlorid (TAC) und Wasser initiierten Polymerisation von Methylmethacrylat (MMA) wurde dilatometrisch durchgeführt. Die Reaktion verläuft über einen Radikalmechanismus; die Anfangspolymerisationsgeschwindigkeit wird durch folgende Gleichung wiedergegeben: \documentclass{article}\pagestyle{empty}\begin{document}$ {\rm R}_{\rm p} {\rm = k[MMA][TAC - H}_{ 2} { O]}^{{ 0}{ .45}}. $\end{document} Die Bruttoaktivierungsenergie der Initiierung wurde auf 4,8 kcal/Mol geschätzt. Aus den kinetischen Ergebnissen und den Daten der Flüssig-Gas-Chromatographie wird ein wahrscheinlich erscheinender Initiierungsmechanismus vorgeschlagen.
    Notes: A kinetic study on the polymerization of methyl methacrylate (MMA) initiated by trichloroacetyl chloride (TAC) and water was made dilatometrically. The reaction proceeds by a radical mechanism, and the initial rate of polymerization is described by the equation: \documentclass{article}\pagestyle{empty}\begin{document}$ {\rm R}_{\rm p} {\rm = k[MMA][TAC - H}_{ 2} { O]}^{{ 0}{ .45}}. $\end{document} The overall activation energy of the initiation was estimated as 4.8 kcal/mole. A probable initiation mechanism was proposed from the kinetic results and the liquid gas chromatographic data.

    Description / Table of Contents: Die durch Trichloracetylchlorid (TAC) und Wasser initiierte Polymerisation von Styrol wurde untersucht. Die Reaktion verlief über einen ionischen Mechanismus, und es bildeten sich Polymere von verhältnismäßig niederem Molekulargewicht. Auf Grund der analytischen Daten des Polymeren wird angenommen, daß die ionische Zersetzung eines als Zwischenprodukt vorliegenden Komplexes aus TAC und Wasser Trichloressigsäure ergibt, die die kationische Polymerisation des Styrols herbeiführt.
    Notes: The polymerization of styrene initiated by trichloroacetyl chloride (TAC) and water was investigated. The reaction proceeded by an ionic mechanism and polymers of relatively low molecular weight were formed. From the analytical results of the polymer, it was suggested that the ionic decomposition of an intermediate complex formed by TAC and water yielded chloroformic acid which induced cationic polymerization of styrene.

    Chemical separation methods for common microbes (1961)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: To collect microbes from suspensions by a process other than centrifugation, it has been found effective to add inorganic and organic electrolytes in the colloidal state. The addition of electrolytes causes a neutralization of charges on the particles in suspension resulting in their coagulation and precipitation. High-molecular-weight compounds which form micelles also promote coagulation and precipitation. It is believed that chemical collection is an extremely efficient method of treatment for the mass production of microbial suspensions.
